Too vague, not actionable, no context. More useful: People can often respond to things within a few frames (1/60 second = 16ms). For some interactions, it's useful to respond within one frame. For others, more latency is acceptable. For yet others, sub-frame latency is required (e.g. VR/AR). Light can move ~3,000 miles in that time, which is a hard limit on latency.
